In the northwest of Khoy in the west Azarbaijan, there are three rocks complexes consist of meta-morphic, ophiolite and non metamorphosed rocks. The grade of metamorphism changes from green-schist to upper amphibolite facies. The study of microstructures shows two foliations; S1 and S2. Mylonitic foliation (Sm) was overprinting them. The main direction of foliations is NNW, which have been generated by three deformations events when Arabian plate were collided into Alborz-Azarbaijan block in later Cretaceous or younger.
